Rewinder tools to assist with (re)winding spools.

Designed to print flat without supports and no cleanup required. The base cone fits snugly onto the threaded shaft. The hexagonal end allows the use of a drill to help wind the spool. The clearances are set very tightly, you may need to adjust the size very slightly depending on your printer.

The small rewinder can fit spools with an opening from 7mm to 24mm. The spool height depends on the inner diameter, up to 50mm. It's useful for small spools like solder.

A large rewinder can fit spools with an opening ranging from about 19mm to 90mm. The screw length is about 90mm. It should be useful for re-spooling filament from damaged or non-conforming spools.

Note: The sizes were chosen to suit a specific need. If they're not right for you, send me a message and I'll post new ones.
